J'UUBNAL BOX.

Application filed November 25, 1921. Serial No. 517,701.

To all whom it may concern:

Be it known that JOHN W. ATKINSON, a .citizen of-the United States ofAmerica, residing at Florence, in the county of F lor- 5 ence and Stateof South Carolina, has invented certain new and useful Improvemerits inJournal Boxes, of which the following is a specification.

My invention relates to an improved ournal box.

Among the objects of my invention are; first, to construct a box inwhich a float, a brass and packing, such as are usually required injournal boxes, are not used; second, to reduce the number of partsrequired in a box; third, to simplify the construction of a box in orderto cut down the cost of manufacture and to enable wornout and brokenparts to be easily replaced; fourth, to provide a box in which themaximum of wear of the parts is obtained; fifth, to construct a boxwhich will enable the journal bearings to be taken out of the box easilyand with very little work, and sixth, to materially reduce the usualcost of lubricating the journal.

With these and other objects in view, one embodiment of my invention isshown in the accompanying drawings in which- Figure 1 is a longitudinalsectional view through the journal box.

Figure 2 1s a section on lines 22 of Fi ure 1.

igure 3 is a section on lines 3=3 of Figure 1.

Figure 4c is a view along the lines 4 4", and

Figure 5 is a bearing casing.

The body 1 of my box is made of any suitable material such as cast-iron,and the sides 2, bottom 3, top 4 and a part of the back 5 are integral.The front of the box is closed by a plate 6, which is attached to thebody by bolts 7 sunk in the body and having nuts 8 on the ends thereof.This plate may have under it a suitable gasket or other means, notshown, to make the box oil-tight. In order to inspect the inside of thebox the plate 6 has therein an opening 9, the bottom of which is onabout the same level as the bottom of the end of the journal. Thisopening is closed by a pivoted door 10. Oil may be put into the box bymeans of the opening 9, or by perspective of the roller an opening 11 inthe top of the box closed by a block 12.

The usual journal 13 which has shoulders 14 and 15 thereon extendsthrough the box to near the front thereof. A dust guard 16 slides ingroove 17 in flanges 18 on the sides of the box. A rubber or felt washerl9 fits over the part 13. of the journal as an additional protection forthe inside of the box from dust.

The part 13 of the journal is surrounded by any suitable number of solidroller bean ings 20 made of suitable material, such as case hardenedsteel, six being shown in the form of box disclosed, the ends of whichare spaced apart by two guides 21 and 22 which are practicallyduplicates and in which are suitable grooves 23 for the ends of therollers. The rollers are enclosed by a casing 24: which may be made ofthe same material as the bearings. The front of the casing is closed bya disc 25, screwthreaded in the casing, the disc having an openingclosed by the end of the journal. The only openings into the casing are,therefore, closed by part 13 of the ournal and the'end 13 of the'ournal. The casing is prevented from revolving by lugs26 fitting in?)sockets 27 in the crown part of the box It is the usual practice tofillthe box with oil to about the bottom of the opening 9, lubrication ofthe rollers being facilitated by openings 28.

The box may be dismantled and the casing may be taken out by raising thebox with the usual jack used for such purposes far enough to allow thelugs 26 to clear their sockets 27. It will be noted that the journalseat in the rear wall is made large enough for the journal to assume theproper angle to release the lugs from their sockets (see Figure 4:).

The form of box illustrated is used on a edestal truck, but the box maybe made to be used with other kinds of trucks.

Having described my invention what I plaim and desire to protect byLetters Patent 333 In a structure of the character described, thecombination of a journal, a box body surrounding the end of saidjournal, the top, bottom, sides, and a part of the rear end thereofbeing integral, a one-piece casing in said body, lugs on said casing,sockets in the crown of said box body for the insertion therein of saidlugs when said structure is assembled whereby motion of said casing isrcvented, said casing having closures at the ends thereof seid closureshaving openings therein for the jourml to pass through, roller hearingsin said casing surrounding the end of said journsl, e guide at each endof said rollers,

1 said guides comprising discs with grooves therein for the insertion ofthe ends of said rollers, a removable plate to close the front end ofsaid box, said plate having an opening therein whereby the interior ofsaid box may be inspected, and s removable closure for the rear end ofsaid box.

in testimony whereof I affix my signsture.

JOHN W. ATKINSON.
